The study of fossils is called a. phylogeny b. gradualism c. paleontology d. anthropology e. biogeography 3. To Cuvier, the differences in fossils from different strata were evidence for a. changes occurring as a result of cumulative but gradual processes b. divine creation c. evolution by natural selection d. continental drift e. local catastrophic events such as droughts or floods 4. Darwin proposed that new species evolve from ancestral forms by a. the gradual accumulation of adaptations to changing or different environments b. the inheritance of acquired adaptations to the environment c. the struggle for limited resources d. the accumulation of mutations e. the exponential growth of populations 5. The best description of natural selection is a. the survival of the fittest b. the struggle for existence c. the reproductive success of the members of a population best adapted to the environment d. the overproduction of offspring in environements with limited natural resources e. a change in the proportion of inheritable variations within a population 6. The remnants of pelvic and leg bones in a snakes a. are vestigial structures b. show that lizards evolved from snakes c. are homologous structures d. provide evidence for inheritance of acquired characteristics e. resulted from artificial selection 7. The hypothesis that whales evolved from land-dwelling ancestors is supported by a. evidence from the biogeographic distribution of whales b. molecular comparisons of whales, fish and reptiles c. historical accounts of walking whales d. the ability of captive whales to be trained to walk

e. fossils of extinct whales found in Egypt and Pakistan that had small hind limbs 8. Darwin's claim that all of life descended from a common ancestor is best supported with evidence from a. the fossil record b. comparative embryology c. taxonomy d. molecular biology e. comparative anatomy 9. The smallest unit that can evolve is a. a genome b. an individual c. a species d. a population e. a community 10. Which of the following would not be considered part of the process of natural selection? a. Many of the variations among individuals in a population are heritable. b. More offspring are produced than ae able to survive and reproduce. c. Individuals with traits best adapted to the environment are likely to leave more offspring. d. Many adaptive traits may be acquired during an individual's lifetime, helping that individual to evole. e. Differential reproductive success leads to gradual change in a population. 11.
